(Quick Reference)

withTransaction

Purpose

Allows programmatic transactions using Spring's Transaction abstraction.

Examples

Account.withTransaction { status ->

def source = Account.get(params.from) def dest = Account.get(params.to)

int amount = params.amount.toInteger() if (source.active) { source.balance -= amount

if (dest.active) { dest.amount += amount } else { status.setRollbackOnly() } } }

Description

The withTransaction method accepts a Closure with a TransactionStatus argument. The TransactionStatus object can be used to programmatically control rollback of the transaction.

Refer to the user guide section of Programmatic Transactions for more information.
